Improvement in syringes



PATENT OFFICEo HORATIO N. MATTISON, OF NEW YORK, N. Y.

IMPROVEMENT IN SVRINGES.

Specification forming part of Letters Patent No. 120,525, dated October 31, 1871.

To all whom 'it may concern:

Be it known that I, HoEATro N. MATTIsoN, of the city, county, and State of New York, have invented a new and useful Improvement in Syringes 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference b'eing had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a sectional side view of my syringe without the nozzle. Fig. 2 is a longitudinal central section of my compound nozzle. Figs. 3 and 4 are detached views of the sections of my suctionpipe.

Similar letters indicate corresponding part-s.

This invention relates to a syringe the bulb of which is provided with a socket capable of receiving nozzles of diii'erent size and shape, said nozzles being so formed that they can beinserted into each other for greater convenience in packing the same.

One of my nozzles is made soft and iieXible, so as to enable the patient to use the same with greater convenience than a rigid nozzle. The suction-pipe of my syringe is made in sections, which are united by couplings, so that the length thereof can be increased or diminished, and that the pipe can be taken apart to be packed in the smallest possible compass.

In the drawing, A designates the bulb of a syringe, which is provided at one end with a socket, a, to receive the nozzle, and at the other end with a nipple, b, to receive the suction-pipe. The socket c is provided with two internal screw-threads, c d, one of which is intended to receive the large cylindrical nozzle B and the other either of the small nozzles C or D; and the nozzle O is bored out so that the nozzle D can be inserted therein, a screw-thread, e, being provided in the end of said nozzle C to receive a corresponding thread on the stem of the nozzle D. On the scr shank f of the nozzle D is secured a co or elastic packing piece, g, which iits into the bore of the large nozzle B, and the nozzles G and D can be pushed into the large nozzlefor greater y convenience in packing. The cok? forms a pad, which bears against the shoulder of the screwsocket a when the small nozzles are secured to the bulb A. The body of the nozzle B is made of India rubber or other soft and eXible material, and it is provided with a metallic cap or mouth-piece, It. By these means a nozzle is obtained which can be used without danger of injuring any part of the body 5 and, furthermore, by combining two or more nozzles with the same bulb a syringe is produced for universal use. The suction-pipe E of my syringe is made of several sections, which are united by couplings t', so that the length of the suction-pipe can be increased or diminished to suit the patient; and, furthermore, my suction-pipe can be taken apart in convenient lengths for packing.

What I claim as new, and desire to secure by Letters Patent, is-

l. The arrangement of two screw-threads of different size in the socket c of the bulb A to receive nozzles of diiferent size and shape, substantially as set forth.

2. The arrangement of a screw-thread, c, in the end of the nozzle C to receive a corresponding thread on the stem of the nozzle D, substantially as described.

3. The compound nozzle B G D, constructed as shown and described.
